Currently, trademark fabrics are usually given a style of both paper and cloth by a coating finishing method. Coating finishing is a surface finishing technique for uniformly coating one or more layers of high polymers and the like on the surface of a fabric to endow the fabric with certain functions. There are many processing methods for finishing coatings, and currently, dry coating and wet coating are mainly used in industrial production. With the continuous improvement of living standard, people put forward higher requirements on textiles. The trademark fabric is generally tasteless, if the aromatic microcapsule is added into a coating agent system, the trademark fabric has certain fragrance, and aromatic substances are slowly released in daily life, so that the fragrance retention time is prolonged, and the additional value of the trademark fabric is further improved.
At present, the research aiming at the slow release microcapsule mainly prepares the aromatic microcapsule by a heat curing mode, for example, the invention patent with the publication number of CN108425248A discloses a preparation method of a nanometer temperature control slow release aromatic microcapsule, which takes a phase change material as a carrier and perfume to form a eutectic as a core material, takes a high molecular polymer as a wall material, and prepares the temperature control slow release microcapsule by the heat curing mode; the invention patent with publication number CN100999697A discloses a preparation method and application of a perfume nanocapsule dispersion liquid, which is a method for preparing the perfume nanocapsule dispersion liquid by an in-situ polymerization method by using etherified melamine resin prepolymer as a monomer for forming a capsule wall material.
In the existing preparation method, the aromatic microcapsule is mainly prepared in a heat curing mode, so that the preparation method is not beneficial to energy conservation and emission reduction. If the light curing technology is introduced into the microcapsule technology, the aromatic microcapsule is prepared in a light curing mode, which is beneficial to protecting the environment, saving the energy and simplifying the working procedure.

5-25 parts of essence
0.1 to 1 portion of initiator
2-6 parts of emulsifier
200 portions of water
(2) Preparing oil phase components: uniformly stirring the essence, the active diluent, the oligomer and the initiator in the step (1) in a closed lightproof container at the temperature of between 25 and 30 ℃; the initiator is one of camphorquinone, camphorquinone/tertiary amine, diacyl phosphorus oxide, benzoyl germane derivative, coumarin/tertiary amine/maleimide; wherein the oligomer is one of pure acrylic resin, polyurethane acrylic resin, polyester acrylic resin, epoxy resin and vinyl ether resin;
(3) preparation of water phase components: stirring and activating the emulsifier and the water in the step (1) at the temperature of 40-45 ℃;
(4) raw material emulsification: adding the oil phase component into the water phase component, and emulsifying under stirring and light shielding conditions at 35-45 deg.C to obtain uniform emulsion;
(5) and (3) irradiating the emulsion obtained in the step (4) with blue light for 10-20min at normal temperature under the protection of nitrogen to initiate polymerization reaction, thus obtaining the aromatic microcapsule emulsion.
2. A process for the preparation of fragrant microcapsules for use in the coating of branded fabrics according to claim 1, wherein: the essence fragrance type is one or a mixture of several of jasmine fragrance type, rose fragrance type, cologne fragrance type and sandalwood fragrance type.

A process for the preparation of fragrant microcapsules for use in the coating of branded fabrics according to claim 1, wherein: the active diluent is one or a mixture of more of hydroxyethyl acrylate, isobornyl acrylate, methyl methacrylate, butyl acrylate, hydroxyethyl methacrylate, dicyclopentenyl acrylate, divinylbenzene and styrene.
4. A process for the preparation of fragrant microcapsules for use in the coating of branded fabrics according to claim 1, wherein: the emulsifier is ionic emulsifier.
5. A process for the preparation of fragrant microcapsules for use in trademark fabric coatings according to claim 4, wherein: the ionic emulsifier is sodium dodecyl benzene sulfonate.
6. A process for the preparation of fragrant microcapsules for use in the coating of branded fabrics according to claim 1, wherein: the stirring speed in the step (4) is 10000-.
